I want to have a blood sugar test tomorrow. What to eat today is not clear.

Blood sugar refers to the content of sugar in the blood. Sugar is some monosaccharides and disaccharides, such as glucose, fructose, galactose, ribose and deoxyribose, not to mention that there is generally nothing to eat, as well as maltose and lactose. In other words, what you eat can be broken down into these things, which will affect your blood sugar, such as rice, steamed bread and noodles, sweet potatoes, potatoes and so on. These starchy foods will be converted into glucose when eaten. Of course, some special foods will not produce glucose when eaten. In addition, tomatoes also have this effect.

Let's talk about the human body. If the human body consumes so much sugar every day, it must be adjusted. Otherwise, won't it get sweet when you get old? This adjustment is very fast. After a few hours, generally speaking, it basically returns to normal level after two hours. In other words, as long as you are healthy, you can eat anything today. I'm talking about daily food. Besides, don't eat tomorrow morning, over.
